Mass of water = volume x density
= 22.0 x 1.00 = 22.0 g
Mass of solution = mass of water + mass of X
= 22.0 + 2.30 = 24.3 g
Heat released by reaction = heat absorbed by solution
= mass x specific heat x temperature change of solution
= 24.3 x 4.18 x (25.5 - 12.0)
= 1371.249 J
Moles of X = mass/molar mass of X
= 2.30/56.0 = 0.04107 mol
H = -heat released by reaction/moles of X
= -1371.249/0.04107
= -3.34 x 104 J/mol = -33.4 kJ/mol
Note that H is negative as reaction is exothermic and heat is released
Solution
Mass of water = volume x density
= 22.0 x 1.00 = 22.0 g
Mass of solution = mass of water + mass of X
= 22.0 + 2.30 = 24.3 g
Heat released by reaction = heat absorbed by solution
= mass x specific heat x temperature change of solution
= 24.3 x 4.18 x (25.5 - 12.0)
= 1371.249 J
Moles of X = mass/molar mass of X
= 2.30/56.0 = 0.04107 mol
H = -heat released by reaction/moles of X
= -1371.249/0.04107
= -3.34 x 104 J/mol = -33.4 kJ/mol
Note that H is negative as reaction is exothermic and heat is released
